Description

Technical Field

[0001] This utility model relates to the field of cable restraint technology, specifically to a cable restraint device. Background Technology

[0002] As a core and critical component of modern engineering construction, cables play an irreplaceable supporting role in many important fields such as transportation infrastructure, large-scale buildings, and energy transmission. Taking large-scale bridge engineering as an example, high-strength cables are the main load-bearing system of cable-stayed bridges and suspension bridges, directly affecting the safety and stability of the bridge structure. However, since most cables are exposed to the natural environment for extended periods, continuously subjected to wind loads, rainwater erosion, drastic temperature changes, and various corrosive media, they are highly susceptible to various defects. If these defects are not detected and addressed in a timely manner, they will seriously threaten the safety of the cable structure, shorten the service life of the bridge, and may even trigger major accidents. Therefore, to ensure the safe operation of the cable structure, effectively extend the service life of the bridge, and prevent catastrophic accidents, regular inspection of cables has become a necessary and crucial aspect of engineering maintenance.

[0003] Currently, traditional manual inspection methods still dominate the cable inspection field in China. However, due to the limitations of manual operation, this method struggles to achieve a comprehensive and accurate assessment of the cable structure's condition, resulting in low inspection efficiency, strong subjectivity, and significant safety hazards. While the emerging cable-climbing inspection technology based on robots and intelligent devices has improved the level of automation to some extent, it also faces a series of technical bottlenecks. Besides the basic issue of inspection accuracy, significant problems exist regarding the stability of the robot's cable-climbing mechanism. For example, pulleys are prone to loosening during robot operation, the equipment is unstable, and its adaptability to cables of different specifications and shapes is poor, making it difficult to meet the inspection results required for actual engineering projects.

[0004] In view of this, the present invention aims to provide auxiliary support for cable inspection robots. Through innovative design and technological improvements, it effectively solves the above-mentioned technical problems of robot cable climbing, thereby significantly improving the efficiency, accuracy and reliability of cable inspection, and providing strong technical support for ensuring the safety of engineering structures.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a bridge cable climbing restraint device, which mainly includes a rear fixing rod, a restraint spring device, and a slider-spiral rod system. The main structure of the device is made of lightweight high-strength aluminum alloy or composite material to ensure that it can effectively withstand the tension generated by the spring. The slider-spiral rod system consists of two hooked sliders 2, a spiral rod 4 with left and right opposite threads and a groove in the middle, a high-speed motor 1, a bearing 9, and a layer of slider safety plate 3. The restraint spring device consists of three sets of front and rear double-hook springs. In particular, the middle set is a double opposite-rotation restraint spring 7. The rear hooks of all three sets of springs are connected to the rear fixing rod, the front hooks of the left and right sets of springs are connected to the hooked sliders 2, and the middle set of springs is connected to the middle of the spiral rod. The grooves are hooked together. The rear fixing rod is connected and fixed to other devices through the hook fixing nut block 8. The right end of the spiral rod is equipped with a bearing 9, which is driven to rotate by the motor 1. The two hook sliders 2 can slide synchronously in opposite directions in the part of the spiral rod with opposite threads by means of a ball screw structure. The function of the slider safety plate 3 is to prevent the slider from sliding when the motor 1 stops working. The two sets of front and rear left restraint springs 6 and right restraint springs 5 ​​are hooked to the hook fixing nut block 8 and the hook slider 2 respectively to control the restraint strength. The middle set of double opposite spiral restraint springs 7 are hooked to the rear fixing rod and the middle groove of the spiral rod respectively, which plays a stabilizing and buffering role during the operation of the machine, thereby ensuring the safe operation of the equipment.

[0022] Before conducting any testing, operators must manually adjust the roller spacing of the testing equipment to determine the optimal installation position. Then, the three sets of restraint springs are connected to the slider-screw system, and the safety testing device is thoroughly inspected and tested. Once preparations are complete, the entire monitoring device is fixed around the cable to be tested. The screw 4 is rotated by the control motor 1, and the rolling screw structure drives the two sets of sliders 2 to move synchronously in opposite directions along the thread. During this process, the tension of the restraint spring system on the testing device rollers is adjusted to gradually raise the rollers and clamp and fix the cable.

[0023] When the cable diameter changes, the screw rod can be rotated by continuously controlling motor 1, causing the restraint spring to extend and retract to adjust, thereby adaptively matching the change in cable diameter and effectively avoiding the risk of equipment movement being obstructed or parts being damaged due to sudden changes in cable diameter.

[0024] In terms of equipment structural design, the slider 2 internally adopts a ball screw drive structure. This structure, with its efficient and stable transmission characteristics and excellent synchronization performance, significantly improves the equipment's operating accuracy and stability, and greatly extends its service life. The intermediate restraint spring group 7 employs a double-helix spring design, composed of two springs with opposite directions of rotation and different stiffnesses. This design not only effectively buffers external impact loads and provides reliable protection for equipment components, but also has a redundancy backup function. Even if one spring fails, the other spring can still maintain the basic function of the spring system, thereby significantly improving the overall reliability and safety of the spring device.

[0025] The working principle and beneficial effects of this invention are as follows: This device controls the rotation of the helical rod to drive the slider to move, adjusts the tension of the restraining spring to clamp the cable, and can adapt to changes in cable diameter. In terms of structural design, the slider adopts a ball screw drive structure to improve performance, and the intermediate restraining spring group adopts a double-helical spring design to enhance stability and safety. It aims to assist cable inspection robots, improve the efficiency, accuracy, and reliability of cable inspection, and ensure the safety of engineering structures.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
